Let A be a matrix with independent rows. A. Show that AAT is invertible. B. Show that if b is any vector in Col(A), then the equation Ax = b has a solution in Row(A) given by xR = AT (AAT )โ1 b. (The matrix AT (AAT )โ1 is called the pseudoinverse of A, and is usually denoted by A+ . It is a right inverse of A, and coincides with the two-sided inverse Aโ1 if A is square.) c. The mapping of Col(A) to Row(A) given by xR = AT (AAT )โ1 b is an isomorphism
